Quick Methods To Improve The Battery Life Of Your Samsung Phone

Battery life is dependable on the usage of a battery and device care, and various mobile phone batteries differ in battery life. You can find the battery life of your phone on the device user manual.

We will now jump into discussing how you could improve and save the battery life and health of your phone through various methods.

1-Brightness level

High-level display brightness causes the increase in battery drain of your Samsung phone. One of the easiest methods to extend the battery life of your phone is by reducing the screen brightness.

Here’s how it is done:

  1. Open your phone.
  2. On your home screen, swipe down from the top of your screen.
  3. Drag the brightness slider toward the left side.

2-Screen Time-Out

Prolonged screen time-out also causes severe battery drain on your device. Battery health significantly benefits from low screen time.

To reduce the screen time-out on your phone, follow the steps below.

  1. Head over to Settings on your phone.
  2. Go to Display settings.
  3. Tap on the Screen Time-out option.
  4. Set your preferred Time-out. It is recommended to set it up to 30 seconds in the display settings.

3-Get Rid Of Unused Apps

There are always some unnecessary apps that are present on our phones for no actual purpose. They may run in the background and drain your phone’s battery, so it’s best to limit apps that are present on your device.

To uninstall those unused apps on your phone, follow the steps below.

  • On your phone’s home screen, long-press the app.
  • Then, either drag it to the top of your screen to the “Uninstall” option or simply tap the Uninstall icon.

Unfortunately, not every app can be uninstalled on your phone, so you have to disable those apps to save battery and increase battery life. To put those unused apps to sleep, follow the steps below.

  • Long-press the app.
  • Then, drag it to the Disable option on top of the display, or select the Disable icon.

4-Turn Off Always On Display (AOD)

Always On Display or AOD uses AMOLED displays to allow you to see particular information even when your device’s screen is Off. It enables you to check basic information like dates and times easily without enabling the display.

Any activity that causes your phone to turn all the time will consume the device’s battery. You can choose to turn off this setting or set a schedule for it to turn on and off automatically.

Follow the steps below to turn off AOD.

  • Head over to Settings on your device.
  • Then, go to the Lock screen and security.
  • From there, select the Lock screen and then the Always On Display setting.
  • Toggle the AOD switch off.

To set a schedule for AOD, just tap the option “Set Schedule” below the Home Button option.

5-Enable Power Saving Mode

Power Saving mode prevents the extra drain of battery power from your device and keeps the limited CPU speed minimum, reducing the brightness on the screen and turning off the touch key light.

Power Saving mode differs in various devices, but it generally closes all the unnecessary apps and screens so that you can considerably increase the timing of your device’s battery usage. Limiting the maximum CPU speed of your device increases the battery life as well as prevents any battery drain.

You can turn on Power Saving mode manually; you can set it so your device can go into Power-Saving mode automatically.

  1. Head over to Settings from your home screen.
  2. Go to Device Maintenance.
  3. And then, Battery. Now you can enable the Power Saving mode.

6-Turn Off Wi-Fi and Mobile Data

Unnecessary turning on the Wi-Fi or cellular data may cause a significant drain on your device’s battery. Turning on airplane mode when you aren’t using the internet also helps in improving the battery life.

To turn them off, slide down from the top of your screen and simply toggle both off.

7-Enable Dark Mode

Samsung smartphones’ OLED displays are flaky and beautiful, especially when it is paired with a 120 Hz screen refresh rate. Apart from the amazing screen-viewing experience, OLEDs also help in saving battery life.

Enabling the dark mode on Samsung’s OLED significantly reduces the battery drain. OLEDs lack a backlight and, as a result, draw limited power when dark pixels are displayed.

To enable the dark mode on your device, follow the steps below.

  1. Head over to Settings on your phone.
  2. Tap Display settings.
  3. Then, turn on the Dark Mode on your screen.

8-Disable Nearby Device Scanning

Nearby Device Scanning prompts your Samsung phone to search for available devices within reach occasionally and shows a notification when it detects one. This feature is helpful, but it is not that necessary to let it drain your battery.

To turn off this feature, follow the steps below.

  1. Head over to Settings.
  2. Then, tap Connections.
  3. Next, More Connection settings.
  4. Finally, Toggle off the switch for Nearby Device Scanning.


In essence, our beloved smartphones are the lifeline of our digital era, but they, too, need some TLC to stay powered up. With simple tweaks like lowering brightness, managing apps, and optimizing settings, you can revitalize your Samsung Galaxy’s battery life. Let’s bid adieu to the battery anxiety and embrace these easy, human-powered techniques to keep our digital companions energized longer. Remember, it’s not always about the capacity but how smartly you manage it. After all, the power to enjoy longer screen time is now literally in your hands!
